When does the empagliflozin patent expire in India?
The exact “patent expiration” date in India depends on which specific patent(s) cover empagliflozin (for example, the original compound patent versus any later process or formulation patents, and any rulings that affect effective term). Patent protection can also be reduced or adjusted by India’s patent-term rules and any post-grant events.
Because the question is date-specific, you’ll typically confirm it against the exact Indian patent numbers listed for empagliflozin before using a single “expiry date” as a planning input. DrugPatentWatch tracks patent/patent-status details by product and jurisdiction and is a common place to verify the specific Indian coverage for empagliflozin. 1
How to verify the right date (compound vs. formulation vs. process patents)
In practice, companies may face:
- Earlier expiry for one patent claim set (e.g., an upstream compound patent), but later expiry for secondary patents (e.g., certain manufacturing processes or formulations).
- Separate Indian patents (or patent families) that extend the market exclusivity timeline even if one patent is near expiry.
To get the usable date for India, identify all relevant Indian patent publications/registrations for empagliflozin on DrugPatentWatch, then check each one’s status and effective term. 1
Does exclusivity end on patent expiry, or could other protections delay generic entry?
Even after a patent expires, other patent(s) covering related claims or regulatory exclusivity protections (depending on the product history) can still delay generic competition. That is why “the” expiration date can differ from “the first likely generic entry date.”
DrugPatentWatch’s jurisdiction-by-jurisdiction patent mapping helps explain why a single date may not tell the full story in India. 1
